Not sure if I'll take that step ... but something to muse on. Not too worried about the soldering having done surface mounts quite a bit previously, more the cost issue that holds me back ;)

The value of the surface mount resistor is printed on it. I happened to have those values in hand or I might not have bothered. Also it's quite easy to do a fairly neat job in the installation, there's plenty of room to get the resistors quite close to the solder pads - I shortened the legs quite a lot, bent them carefully, and sleeved in PTFE. Sorry can't post a picture as I've never worked out how to do that on this site, and anyway the unit is back in its case, and I'm listening to a podcast now.

Sorry, but is it the R5 & R7 on the PI or the in the DAC PCB?

They are on the DAC board.

Oh, read it on other page it was on the PI itself, can't really use this mod on the Sabre dac then. Thanks.

Hi Graeme,

Nice one. I'd certainly like to see how you've done the job, and I'm sure others would too, as it sounds very neat. Therefore, if you would take a pic and email it to me, I'll post it here for you! PM me for my email address :)

Marco.

No worries... £20? Bloody tight-wad! :ner:

Marco.

Thank you for your reply.
I'm unsure if you were referring to the one I was thinking of : https://www.hifiberry.com/product/hifiberry-dac-pro/
It sports Twin Clock crystals and No heaphone 'stuff'
Slightly cheaper (irrelevant) than the Iqaudio and a bit easier to obtain (not so irrelevant) .. on this side of the Planet.

As digression and hopefully not into religious territory; I have had good success using Batteries as P Supplies for low voltage needs (if you can count battery maintenance hassles as inconsequential :-).
A set of round cells on hand .. 4.8 v 3300mah that can output 30 Amps (measured) with a flat curve down to discharge (1 volt) level before dropping output like a stone.
Seem like a possible Pi Power candidate?

Just another mod on the list of competing mods.. at the moment fairly low down in the priorities :D

Ah, gotcha... Dunc had already modded his Pi, so I just took the notion and did mine. Glad I did though, as it's a pretty worthwhile sonic upgrade :)

Marco.

I just saw this by a guy on a DIY forum: http://internetofmusic.nl/home/

It's a Pi with DAC (might be Hifibury+?) and a 2 channel, 30W Class-D Hypex amplifier in one box, ready to go with wifi and your choice of software, shown here with the case open. Looks to be priced at about £210 + VAT . Doing a quick parts add up with estimations on the case and bits, that works out to about £50 or so for someone to build and set it all up for you - not bad at all :
